YONCALLA, Ore. -- Douglas County Sheriff's Office is investigating after its Tactical Team found a man dead at a Yoncalla residence having suffered a self-inflicted gunshot wound in what authorities are calling an "attempted murder/suicide" that also sent the man's girlfriend to the hospital.

Around 4 p.m. Saturday 4:00 p.m., the 911 center received a call from Brenda Schaff, from Junction City, stating she had been shot two times by her boyfriend at his residence on Cox Road in Yoncalla, according to the Sheriff's Office news release.

Sheriff's deputies and Oregon State Police Troopers responded and officers located the woman outside the residence. She told them that her boyfriend, 53-year-old Bruce Nelson of Yoncalla, shot her two times during a domestic disturbance at the Cox Road residence. She was transported to Riverbend Hospital in Springfield where she was treated for non-life threatening injuries, police said.

Authorities say deputies and Sheriff's Office crisis negotiators made phone contact with Nelson and attempted to get him to surrender. During negotiations, several gunshots were heard coming from the residence, the last one being heard at about 6:00 p.m., police said.

At about 7:14 p.m., Sheriff's Office Tactical Team members found Nelson on the front porch of the residence. Police say he was dead from a self-inflicted gunshot wound.

Schaff was taken to RiverBend Hospital for non-life threatening injuries.
